SYSTEM FOR THE PRODUCTION OF OIL GAS.

' Application filed March 11, 1924. Serial no. 698,419.

This invention relates to a system for the production of gaseous fuel and its primary I object is to provide a practical and economical method of utilizing a volatileliquid hydro carbon in generating a gaseous mixture adapted for use as afuel or an illuminant.

A further object of the invention is to produce a fuel of the above stated nature of which aqueous vapor, preferably in the form of steamyis an element and still another object is to provide a system of co-operative devices for the production of a. fuel gas by a novel method of difiiu sing its components.

The method consists briefly in causing the forcible contact of an atomized volatile liquid hydrocarbon and a vapor under pressure inan enclosed space, whereby to effect a rapid and complete volatilization of the liquid while it is being diffused throughout the vapor. p

The generated hydrocarbon gas is com ducted fromthe mixing space to the burners of a stove or other heating appliance either directly or bymeans of a storage reservoir or it may if so desired be utilized as an illuminant by passing it to the burner of a lamp.

An embodiment of a system suitable for use in the performance ofthe process has been illustrated in the accompanying drawings in which like characters of reference designate corresponding parts-throughout the several views and in which i c v Figure 1 represents in sectional elevation the system in its preferred form for the utili-' zation of steam andgasolene or other liquid hydrocarbon; l

FigureQ, an enlarged sectional elevation of the mixing chamber of the system; I

Figure 3, an enlarged vertical sectional view of a check valve adapted for use in preventing the return flow of fluids passing through the system; and

Figure 4, a view similar to Fig. 3 of a pressure regulating valve suitablejfor use in the system. c

Referring to the drawings, the numeral 5 designates a steam boiler heated by a gas burner 6 of conventional construction and provided with a steam outlet which through the medium of a pipe 7 isconnected with the gas generating chamber 8; In the form of the invention illustrated in Fig. 1 of the drawing all of the steam from the boiler 5 is used in the production of the gaseous fuel.

The end of the pipe extends into the chamher in direct opposition to a valve-controlled nozzle 9 at the extremity ofa pipe 10 which connects with a source of volatile liquid hydrocarbon such as gasolene, represented by the tank 12. V

The gas generating chamber has an oil and gas outlet 13 which by means of a pipe 13 is connected with a storage reservoir 1 1 from where the gaseous fuel is connected to the burners of a stove or other heating appliance by means of a pipe 15.

In the construction shown in the drawing a pipe 16 connected with a second outletof the reservoir 1% conducts a part of the gaseous fuel generated in the operation of the system to the burners of the boiler, pressure regulating valves 17 and 18 of the type illustrated in Figure 4, are connected in the pipes 7 and 10 leading from the boiler and the gasolene tank to the mixing chamber, check valves 19 and 20such as that shown in Figure 3, preventthe return flow of fluid through the pipes 13 and 10 and hand-valves 9.1 and 22 control the supply of fuel to the burners through the pipes 15 and 16.

It is advantageous that the hydrocarbon liquid enter the mixing chamber under pressure and the means for creating this pressure have been indicated in the drawing by' a simplepump 23 connected with the upper portion of the tank 12 through the medium of a pipe 2 1'. We desire it understood, however, thatany other means to forcibly introduce the volatile liquid into the mixing chamber may be employed within the spirit of our invention.

A preferred arrangement of the pipes in the mixing chamber has been illustrated in Figure 2 in which the nozzle 9 at the end of the pipe leading from the gasolene tank is extended into the pipe throughwhich the thus mounted performs the same function as the nozzle-valve shown at 29 in Figure 1. The discharge end of the steam pipe forms a i a j except the valve 25,

In the operation o'f the system, the violent eontaot of the two fluids entering the mixing ohainberunder pressure, causes their inti mate diliusion andintermixture in gaseous tubulargsteam inlet}? for the-gas generating chamber, andthesteam inlet extends through one of the walls of the gas generating'c hamberpast the oil gas outlet l3 zand terminates short of theoppositewall'through which ,exe
